Odor Abatement

Fuel oils, asphalt, slops and heated feedstocks can all be sources of objectionable odors at terminals and tank farms. These odors often result in community complaints and workplace concerns. Increasingly, facilities are looking for odor control solutions in which the odor is neutralized rather than simply masked. Nalco Champion odor abatement additives interact with volatile organic components (VOCs) to modify the partition into the vapor phase and inhibit the formation of additional VOCs.

Tolerance for nuisance odors has decreased in recent years as refineries, storage facilities and communities reside in closer proximity to each other. Odor complaints by neighborhoods are taken very seriously. Refiners and tank farm operators are looking for solutions that don’t just mask these odors, but instead significantly reduce their severity and frequency.

Nalco Champion odor abatement additives are used to decrease the odor that emanates from storage tanks as a result of volatile organic compounds (VOCs). Our additives:

May be injected directly into the hydrocarbon to provide lasting odor neutralization

Function by interacting with VOCs to decrease their partitioning into the headspace of storage tanks

Scavenge oxygen in order to prevent the formation of additional VOCs

Have successfully reduced dilution to threshold ratio vs untreated samples by an order of magnitude

Can be added at elevated temperatures to protect a variety of hydrocarbons from odor complaints, and do not cause any negative impacts in asphalt, crude oil, fuel oil or other hydrocarbon products
